SMQKING PIPE DEVICE Application filed June 22, 1928, Serial No. 373,021.Renewed June 4, 1932.

This invention relates to an improved smoking pipe of the variety whichis especially constructed to embody details which coopcrate insubjecting the smoke to a unique and tortuous passage in such a manneras to hold the smoke to retard it and to cool it. In carrying theinvention into effect, I have evolved and produced a sim lifiedstructure which may be incorporate in a pipe which in general externalappearance, is the same as 1 many of the similar devices on the market.

More specificall speaking, I provide a pipe wherein the owl is composedof two parts, namely, a tobacco receptacle, and

smoke cooling and saliva collecting cup. In addition,'I have found itexpedient to embody within the stem of the pipe, aluminum.

or metallic inserts so constructed as to further subject the smoke to aretarded action, said insert having the additional function of providinga saliva collector or trap whereby to keep undesirable nicotine juicesfrom the mouth of the user.

The features and advantages will become more readily apparentfrom thefollowing description and drawing:

In the drawing Figure 1 is a view in sectional elevation of a com letepipe constructed in accordance with tlie present invention.

Figure 2 is an enlarged fragmentary sectional view showing the featuresofthe nicotine collecting trap.

In the drawing the reference numeral 3 designates generally the bowl.This comprises an upper section 4 which is made to provide a receptaclefor the tobacco. This has a screw threaded nipple 5 at its bottom and arestricted smoke port 6. The nipple 40 5 is tapped into the screwthreaded upper end portion of a head 7 on the forward end of the body 8of the pipe. This head is made to provide a smoke cooling chamber as at9. The body includes the usual stem portion. Within this portion is themetallic insert generally designated by the reference char acter 10. Asdetailed in Figure 2, this is preferably constructed of aluminum andmade of two parts, namely, an elongated 5 cylinder 11 of uniformdiameter which is open at one end and closed at its opposite end, whichdefines a saliva collectin trap 12, and an attaching or coupling device.The coupling is indicated by the reference numeral 13, and comprises ascrew threaded member which is threaded into a socket in the bakelitemouthpiece 14, and into the internally threaded open end of the cylinder11. In addition it includes an extension 15, which extendsconcentrically into the interior of the saliva trapping chamber 12. Theleft closed end portion of the cylinder is 1'0- vided with a smokeint'ake passage 16 w ich communicates with an inwardly projectingtubular extension 15a. Both of these extensions are in longitudinalspaced relation and concentrically arranged within the interior of thecylinder. The left hand end portion of the cylinder is formed with anexternal circumferential groove 17 to accommodate a packing (not shown)to seal the joint between the walls of the bore and the cylinder 11. Infact, the couplin 13 is threaded into the socket in the mout ipiece 14,then the cylinder 11 is threaded on to the projecting end portion ofthis coupling so that the parts assume the assembled relationship seenin Figure 2.

In accordance with the invention, the tobacco is first placed in theupper part 4 of 30 the sectional bowl. Here it is drawn by suction inthrough the metallic insert 10. Here it is acted upon by the features 15and 16 as well as the chamber 12. The moisture and saliva accumulate inthe chamber, and are prevented from flowing back through the bore in themouthpiece 14. The result is that the user is assured a pleasant,convenient, sanitary, and cooling as well as a tasty smoke.

It is believed that. persons familiar with smoking appliances of thisclass will be able to obtain a clear understanding of the same afterconsidering the description in conjunction with the drawing. Therefore,a more lengthy description is believed to be unnecessary.

Minor changes in shape, size, and rear: rangement of details coming withthe field of invention claimed is resorted to in actual practice ifdesired.

Having thus described my invention, I claim as new is An appliance forinsertion into tb stems of smoking pipes comprising the cylindricalbody, the interior of which constitutes a saliva trap, tubes extendinginwardly from opposite ends of said body and in spaced relation to theside walls thereof, said tubes terminating in spaced relation withrespect to each other, and an external groove provided in saidcylindrical body adjacent one end thereof and adapted to receive apacking for sealing the joint between the cylindrical body and the borein the stem into which the cylindrical body is adapted to be inserted.

In testimony whereof I afiix my signature.

ANTHONY J. MAURO.
